Detailed Description

In order that the above-mentioned objects, features and advantages of the present application may be more clearly understood, the solution of the present application will be further described below. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced other than as described herein; it is to be understood that the embodiments described in this specification are only some embodiments of the present application and not all embodiments.

Referring to fig. 1 to 4, the present embodiment provides a battery cover rolling device of a mobile terminal. The battery cover 3 has two opposite first sides 31 and two opposite second sides 32, and the length of the first sides 31 is greater than that of the second sides 32. The mobile terminal in this embodiment may be, for example, a mobile phone, or may also be other terminal equipment with a battery cover, such as a tablet.

The battery cover rolling device of the mobile terminal specifically comprises a rolling assembly 1. The battery cover rolling device of the mobile terminal provided by the embodiment is directed to the battery cover 3 with a rectangular cross section. It is understood that the first side edge 31 is a long edge extending in the length direction of the battery cover 3, and the second side edge 32 is a short edge extending in the width direction of the battery cover 3.

In particular, the rolling assembly 1 comprises two first wheels 11, two second wheels 12 and a support structure 13 for supporting each first wheel 11 and each second wheel 12. Wherein, the two first rotating wheels 11 are positioned between the two second rotating wheels 12; the first rotating wheels 11 correspond to the first side edges 31 one by one, and the first rotating wheels 11 can rotate axially to roll the corresponding first side edges 31. The second rotating wheels 12 correspond to the second side edges 32 one by one, and the second rotating wheels 12 can rotate axially to roll the corresponding second side edges 32, so that the height of the bottom surface of each first rotating wheel 11 is higher than the height of the bottom surface of each second rotating wheel 12.

Illustratively, when rolling the battery cover 3 of the mobile terminal, the first roller 11 is first brought into correspondence with the first side 31 of the battery cover 3, and the first roller 11 is rotated to roll the first side 31, i.e., the length direction of the battery cover 3. After the first side edge 31 is rolled, the second rotating wheel 12 is made to correspond to the second side edge 32 of the battery cover 3, and the second rotating wheel 12 is rotated to roll the second side edge 32, that is, the width direction of the battery cover 3 is rolled.

That is to say, in the whole rolling process of the battery cover 3, the rolling of the battery cover 3 in two directions can be realized by using only one rolling device of the battery cover 3 without replacing rolling equipment, so that the investment of the rolling equipment is reduced to a certain extent, and the cost of the rolling of the battery cover 3 is reduced. Set up like this, simple structure, convenient operation, and battery cover 3's roll extrusion is efficient.

For example, referring to fig. 3, when the rolling device for the battery cover 3 is used to roll the second side edge 32, a certain gap is formed between the first roller 11 located between the two second rollers 12 and the battery cover 3, that is, both the two first rollers are in a suspended state. With continued reference to fig. 4, when the rolling device for the battery cover 3 is used to roll the first side edge 31, the second rollers 12 outside the two first rollers 11 are located outside the battery cover 3, i.e. both second rollers are in a suspended state.

That is, by making the height of the bottom surface of each first rotating wheel 11 higher than the height of the bottom surface of each second rotating wheel 12, it is possible to effectively avoid interference with the second roller when the first rotating wheel 11 rolls the first side edge 31, and interference with the first roller when the second rotating wheel 12 rolls the second side edge 32, thereby ensuring effective implementation of the rolling process of the battery cover 3.

In the battery cover rolling device of the mobile terminal provided by this embodiment, the rolling assembly 1 is provided, and the rolling assembly 1 includes two first rotating wheels 11, two second rotating wheels 12, and a supporting structure 13 for supporting each first rotating wheel 11 and each second rotating wheel 12, and the two first rotating wheels 11 are located between the two second rotating wheels 12; the two first rotating wheels 11 correspond to the two first side edges 31 of the battery cover 3 one by one, and the first rotating wheels 11 can rotate axially to roll the corresponding first side edges 31; the two second rotating wheels 12 correspond to the two second side edges 32 of the battery cover 3 one by one, and the second rotating wheels 12 can rotate axially to roll the corresponding second side edges 32; wherein, the length of the first side edge 31 is greater than that of the second side edge 32; meanwhile, the bottom surface of each first runner 11 is located at a height higher than that of each second runner 12. When the battery cover 3 of the mobile terminal is rolled, the first rotating wheel 11 of the rolling device of the battery cover 3 is firstly made to correspond to the first side 31 of the battery cover 3, and the first rotating wheel 11 is rotated to roll the first side 31, that is, the length direction of the battery cover 3 is rolled, and after the first side 31 is rolled, the second rotating wheel 12 of the rolling device of the battery cover 3 is made to correspond to the second side 32 of the battery cover 3, and the second rotating wheel 12 is rotated to roll the second side 32, that is, the width direction of the battery cover 3 is rolled. That is, in the entire rolling process of the battery cover 3, the rolling of the battery cover 3 in two directions can be performed by using only one rolling device for the battery cover 3 without replacing the rolling device, thereby improving the rolling efficiency of the battery cover 3 to some extent. Meanwhile, the height of the bottom surface of each first rotating wheel 11 is higher than the height of the bottom surface of each second rotating wheel 12, so that the interference between the first rotating wheel 11 and the second rotating wheel when the first rotating wheel 11 rolls the first side edge 31 and the interference between the second rotating wheel 12 and the first rotating wheel when the second rotating wheel 12 rolls the second side edge 32 can be effectively avoided, and the effective implementation of the rolling process of the battery cover 3 is ensured.

Referring to fig. 2, the centers of the first and second runners 11 and 12 are at the same height, and the diameter of each first runner 11 is smaller than that of each second runner 12, so that the bottom surface of each first runner 11 is higher than that of each second runner 12. With the arrangement, the rolling assembly 1 is simple in structure and convenient to operate.

Of course, the centers of the first runners 11 and the second runners 12 may not be at the same height, that is, the centers of the first runners 11 and the second runners 12 may have a certain height difference, and the size relationship between the diameter of the first runners 11 and the diameter of the second runners 12 may be adjusted according to the height difference so that the bottom surface of the first runners 11 is higher than the bottom surface of the second runners 12.

In some embodiments, the supporting structure 13 includes a supporting frame 131 and an axially rotatable shaft 132 disposed on the supporting frame 131, and each of the first rotating wheel 11 and each of the second rotating wheel 12 are fixed on the shaft 132, so that when the shaft 132 rotates, the first rotating wheel 11 and the second rotating wheel 12 are driven to rotate.

That is, the first wheel 11 and the second wheel 12 are fixed to the same shaft 132 and rotate synchronously with the shaft 132. By the arrangement, the whole rolling assembly 1 is simple in structure and convenient to operate, and the first rotating wheels 11 and the second rotating wheels 12 are good in synchronism and consistency when rotating, so that the rolling effect of the rolling assembly 1 on the battery cover 3 can be improved to a certain extent.

In specific implementation, in order to monitor the rolling force of the rolling component 1 on the battery cover 3 and ensure the rolling effect of the battery cover 3, the pressure sensor 4 is arranged on the support frame 131. Wherein, the pressure sensor 4 is used for detecting the pressure between the rolling assembly 1 and the battery cover 3.

With this arrangement, the operator can easily adjust the pressure between the rolling assembly 1 and the cell cover 3 according to the result of the pressure sensor 4 to ensure good rolling of the cell cover 3.

Since the force effects are mutual, when the rolling assembly 1 rolls the battery cover 3, the battery cover 3 also applies an upward force to the first rotating wheel 11 or the second rotating wheel 12, so that the rolling assembly 1 has an upward movement tendency. In order to ensure the rolling effect of the rolling assembly 1 on the battery cover 3 during the upward movement and the subsequent downward movement of the rolling assembly 1, it is necessary to ensure that the rolling assembly 1 can only move in the vertical direction.

In some embodiments, a balancing member 6 is disposed on the supporting frame 131, and the balancing member 6 is used for adjusting the levelness of the rolling assembly 1 during rolling.

By the arrangement, the levelness of the rolling assembly 1 is guaranteed, and the phenomenon that when the rolling assembly 1 is unbalanced in the horizontal direction, only one first roller is in contact with the corresponding first side edge 31 or only one second roller is in contact with the corresponding second side edge 32, so that the unilateral stress condition of the battery cover 3 is caused, and the rolling quality of the rolling assembly 1 on the battery cover 3 is improved to a certain extent.

The linear bearing 62 is a linear motion system with high precision, and in specific implementation, the balance member 6 includes a vertically arranged guide post 61 and the linear bearing 62 penetrating the periphery of the guide post 61. Wherein, make support frame 131 connect in the bottom of guide post 61, and linear bearing 62 is used for making guide post 61 drive rolling component 1 and moves in vertical direction to the levelness of adjustment rolling component 1.

The linear bearing 62 is arranged, so that the guide post 61 can only move in the vertical direction, and the guide post 61 can ensure that the rolling assembly 1 is driven by the guide post 61 to move vertically and vertically in the up-and-down moving process of the rolling assembly 1. The arrangement is simple in structure, and the levelness adjusting effect of the rolling assembly 1 is good.

Of course, the balance member 6 may also include a slide rail, which is vertically disposed and is used for the slide block to move, and the support frame 131 is connected to the slide block, so that the rolling assembly 1 can only move vertically along the slide rail under the driving of the slide block.

Referring to fig. 2, the supporting frame 131 specifically includes a top plate 133 and a bottom plate 134 located below the top plate 133, and two sides of the bottom plate 134 have side plates 135 for rotatably connecting with the rotating shaft 132. In specific implementation, two through holes may be formed in the top plate 133, and the two through holes are disposed at intervals in the extending direction of the top plate 133, so that the two guide posts 61 and the two linear bearings 62 are both in one-to-one correspondence with the two through holes. Specifically, the linear bearing 62 on the periphery of one of the guide posts 61 is passed through the through hole, and the linear bearing 62 is fixed in a lap joint on the top surface of the top plate 133, and the bottom end of each guide post 61 is connected with the top surface of the bottom plate 134, so that the fixation to the guide post 61 and the linear bearing 62 is realized.

In specific implementation, an elastic buffer member 5 is further arranged above the supporting frame 131, and the elastic buffer member 5 can float up and down and drive the supporting frame 131 to move up and down so as to adjust the pressure between the rolling assembly 1 and the battery cover 3.

The elastic buffer piece 5 is arranged, so that the impact force of the rolling component 1 on the battery cover 3 can be counteracted, the rolling effect of the rolling component 1 on the battery cover 3 is ensured, and the battery cover 3 is well protected.

The elastic buffer 5 may be a spring, an elastic cushion pad, or other structures having a buffering function. Referring to fig. 2, when the elastic buffer 5 is a spring, the spring is inserted into the bottom of the guide post 61 to guide the compression deformation of the spring. Meanwhile, the top end of the spring is connected to the bottom end of the linear bearing 62, and the bottom end of the spring is connected to the top surface of the bottom plate 134.

Referring to fig. 1, the battery cover rolling device of the mobile terminal further includes a first horizontal rail 8, and the rolling assembly 1 can move back and forth along the extending direction of the first horizontal rail 8 to adjust the position of the rolling assembly 1 relative to the battery cover 3.

The position of the rolling assembly 1 can be conveniently adjusted by arranging the first horizontal rail 8, so that the automation degree of the rolling device of the battery cover 3 is improved to a certain degree. For example, when the battery cover 3 needs to be rolled, the rolling component 1 can be moved towards the direction close to the battery cover 3; and after the rolling of the battery cover 3 is finished, the rolling component 1 is moved towards the direction far away from the battery cover 3.

Meanwhile, the battery cover rolling device of the mobile terminal further comprises a vertical rail 9, the vertical rail 9 can reciprocate along the extending direction of the first horizontal rail 8, and the rolling assembly 1 is arranged on the vertical rail 9. When the battery cover 3 needs to be rolled, the vertical rail 9 is firstly moved along the first horizontal rail 8, so as to drive the rolling assembly 1 to move above the battery cover 3. Then, the rolling assembly 1 can reciprocate along the extending direction of the vertical rail 9 to drive the rolling assembly 1 to move downwards and abut against the top surface of the battery cover 3. Finally, when the vertical rail 9 reciprocates along the first horizontal rail 8, the first rotating wheel 11 or the second rotating wheel 12 is driven to rotate, so that the battery cover 3 is rolled.

By the arrangement, the structure is simple, the operation is convenient, and the automation degree of rolling the battery cover 3 and the rolling efficiency can be improved to a certain extent.

Specifically, a first sliding chute is arranged on the first horizontal rail 8, and a first sliding block capable of moving back and forth along the extending direction of the first sliding chute is arranged on the vertical rail 9, so that the vertical rail 9 can move along the first horizontal rail 8. Similarly, a second sliding groove is formed in the vertical rail 9, and a second sliding block capable of moving back and forth along the extending direction of the second sliding groove is arranged on the rolling assembly 1, so that the rolling assembly 1 can move along the vertical rail 9.

The embodiment also provides a battery cover rolling system of the mobile terminal, which comprises a jig 2 for placing the battery cover 3 and the battery cover rolling device of the mobile terminal, and the jig 2 is positioned below the battery cover rolling device of the mobile terminal.

The specific structure and the implementation principle of the battery cover rolling device of the mobile terminal are the same as those of the battery cover rolling device of the mobile terminal, and the battery cover rolling device of the mobile terminal can bring the same or similar technical effects.

For example, as shown in fig. 3 to 4, after the rolling of the second side edge 32 of the battery cover 3 using the rolling device of the battery cover 3 is completed, the rolling device of the battery cover 3 is first moved upward to be separated from the battery cover 3; then, under the driving action of the driving member 22, the jig body 21 and the battery cover 3 located in the jig body 21 are rotated by 90 degrees; then, the rolling device of the battery cover 3 moves downwards, so that the second rotating wheel 12 is abutted against the second side edge 32 of the battery cover 3, and the second side edge 32 is rolled; finally, the rolling process of the entire battery cover 3 is achieved.

By the arrangement, an operator does not need to hold the jig body 21 to rotate; meanwhile, an operator is not required to take out the battery cover 3 after rolling one pair of side edges of the battery cover 3 and put the battery cover into the other jig 2 for rolling the other pair of side edges of the battery cover 3, so that the rolling process of the battery cover 3 is simplified, the waste of manpower is reduced to a certain extent, and the automation of the operation process of the battery cover rolling system of the whole mobile terminal is improved. Meanwhile, the precision of the rotating process of the jig body 21 is high, and the rolling effect and efficiency of the battery cover 3 are improved.
